Обсуждение: A doubt in pgtcl

Dear Sir,I have just started to program in pgtcl.I have to write a procedure for 
connecting to a table and fetching records and inserting them.What should 
I do to catch the error conditions?The postmaster runs in a separate 
terminal and Tcl in another one.The errors may be non existing table 
name,field name or errors like query fetching many rows as result.Please 
give me a solution for this problem.Thanking you.

Yours truly,
Senthil J

[Hummmm, wonder why it didn't have pgsql-interfaces in
the reply-to]


You can use pg_result to get any error info. For
example:

set han [pg_connect ...]

set result [pg_exec $han "SELECT * FROM bogus_table"]

set stat [pg_result $result -status]

if {$stat ne "PGRES_TUPLES_OK"} {
   puts "GOT ERROR: [pg_result $result -error]"
}


HTH,
   --brett
